Diver Skeleton is a Skeleton of a Diver that was killed at the Shark Castle several decades (Or years) ago. He/She wears an Aquaraider helmet, meaning that he/she might have journeyed here at some point and died at the left Golden Gate.
- Another reason that this Diver skeleton could have been part of Aquaraiders is that the Skeleton was holding gems, and the Aquaraiders were looking for treasure.
- The minifig may have nothing to do with Aquaraiders, it may be just that Lego chose that helmet for the diver to wear. And it couldn't wear a Airtank Helmet since only members of the Deep Sea Salvage Crew wore those, and there were only six members of the crew.
- This is the same minifigure that appeared in Aquaraiders 7775 Aquabase Invasion.
